What condition is associated with DBH p.Ala362= (c.1086G>A)?

DBH p.Ala362= (c.1086G>A) is associated with orthostatic hypotension 1 (ClinVar).

How common is DBH p.Ala362= (c.1086G>A) in the general population?

DBH p.Ala362= (c.1086G>A) is ultra-rare (popmax 0.0165%, mid) (gnomAD).

How is Dopamine beta-hydroxylase deficiency inherited?

Typically Autosomal recessive (Orphanet). A genetic counselor can assess individual risk for a family.

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
